Further, as shown in FIG. 1, an operation panel 49 and a detergent charging case 50 are provided on the uppermost portion of the front surface portion 1a of the outer box 1.

  Next, the operation and effect of the drum type washing and drying machine having the above configuration will be described.

First of all, the basic washing and drying functions are “washing”, “rinsing”, “dehydration”,
The “drying” process is automatically executed.

At the time of “washing”, the drain valve 18 is closed, and the washing water (not shown) supplied through the water supply valve 44 in a state where the laundry (not shown) to be put in from the laundry entrance 27 is accommodated in the drum 11.
Is stored in the lower part of the water tank 2 and detergent is introduced from the detergent introduction case 50, and the drum 11 is alternately rotated by the motor 8 in both forward and reverse directions at a low speed of, for example, 50 to 60 [rpm].

Thereby, the laundry is stirred together with the washing water to perform washing. At this time, the baffle 15 sequentially lifts the laundry and the washing water, and promotes the stirring of the washing and the washing water.

At the time of “rinsing”, the drain valve 18 is closed, the washing water is accumulated in the water tank 2 from the water supply valve 44, and the drum 11 is alternately rotated in both forward and reverse directions at a low speed of, for example, 50-60 [rpm] by the motor 8. . As a result, the laundry is stirred together with the washing water to rinse the dirt and detergent attached to the laundry. The rinse water after the rinsing is discharged from the drainage port 17 of the water tank 2 through the drainage valve 18 and the drainage hose 20 to the outside of the machine.

At the time of “dehydration”, the drum 11 is moved to the motor 8 with the drain valve 18 and the water supply valve 44 closed.
Thus, it is rotated in one direction at a high speed of 800 to 900 [rpm]. Thereby, the water contained in the laundry is discharged from the dewatering hole 14 by centrifugal force. This drained water is stored in tank 2
From the drain port 17 through the drain valve 18 and the drain hose 20, it is discharged out of the outer box 1.

At the time of “drying”, the drum 11 is driven by the motor 8, for example, 50-60 [r] as in washing.
pm] at low speeds in the forward and reverse directions, and the hot air heated by the hot air generator 43 is simultaneously blown into the drum 11 from the air supply port 22.

However, during the operations of “washing”, “rinsing”, “dehydration”, and “drying”, the clothes are agitated or centrifugally dewatered to generate centrifugal force, and the drum 11 is moved vertically and horizontally (drum 11
Vibrates in the radial direction of the rotation axis.

Similarly, the water tank 2 vibrates as the drum 11 vibrates. However, since the water tank 2 vibrates in synchronization with the vibration of the water tank 2, the outer peripheral surface of the drum 11 and the inner peripheral surface of the water tank 2 do not hit each other.

On the other hand, the bellows 35 provided in the water tank cover 21 is made of a flexible material, and the bellows part 35a is formed at the intermediate portion, so that it is delayed with respect to the vibration of the water tank 2. Follow, and distort and deform to absorb the amplitude of the water tank 2.

As described above, at the time of “drying”, the fan 38 of the hot air generating device 43 is rotated simultaneously with the rotation of the drum 11 and the heater 42 is caused to generate heat. As a result, the damp air in the drum 11 is removed from the drain port 17 of the water tank 2 by the dehumidifier 36 as shown by the arrows indicating the air flow in FIG.
The air is dehumidified by this dehumidifier 36 and sent to the casing 37 (air flow in the direction of arrow C). And the fan 3 in the casing 37
8 and further heated by the heater 42 in the duct 41 to become hot air of 100 degrees or more (air flow in the direction of arrow D). Then, hot air of about 100 degrees flows from the air supply port 22 provided in the air supply path 22a of the water tank cover 21 toward the position S (shaded portion S) of the lower part 21a that vigorously opposes the air supply port 22 on the water tank cover 21. Blown out (air flow in the direction of arrow E)
(See FIGS. 1, 3, and 6.) A part of the air flow in the direction of arrow E is reflected by the position S, becomes an air flow in the direction of arrow F, and is diffused into the drum 11. Further, a part of the air flow in the direction of arrow E is diffused in the drum 11 as an air flow in the direction of arrow G and is brought into contact with the laundry being stirred to dry the laundry.

Therefore, as shown in FIGS. 1 and 6, the lighting device 24 provided at a position (position other than the position S) different from the blowing direction of the hot air blown from the air supply port 22 has a momentum and the hot air that is hot. Hot air (air flow in the direction of arrow F) reflected at the position S is difficult to hit directly, and the water tank cover 2
1 is convected on the inner circumference and diffused into the drum 11. Then, the air flow in the directions of arrows F and G supplied into the drum 11 merges in the vicinity of the drain port 17 and becomes the air flow in the direction of arrow A again, and the air in the drum 11 is circulated and dried. Is done.

  Here, the irradiation range of LED24a which the illuminating device 24 has is demonstrated.

This LED 24a can be irradiated even when the drum type washing and drying machine is in operation in accordance with the switch operation of the operation panel 49. In addition, since the illumination device 24 is attached to the water tank cover 21 so that the light has a directing direction obliquely downward in the drum 11, as shown in FIG. 2, an irradiation range X (shaded portion X in the drum 11) by the LED 24a. Can be irradiated with light (from the front of the drum toward the depth). Part of the light emitted from the LED 24a is reflected by the white silk-printed surface (shaded portion T) of the base 24a1 and the mirror-finished surface of the storage portion 24d1 (see FIG. 5D), and the drum Head in.

According to the first embodiment of the present invention as described above, the lighting device 24 is provided on the water tank cover 21 formed of a rigid material, so that it does not deform even with respect to the vibration of the water tank 2 or the drum 11 and is greatly increased. Since it is not distorted, the attachment port 21c of the illuminating device 24 does not spread or the illuminating device 24 does not come off. Therefore, water leakage is not induced and watertightness can be reliably maintained.

Further, since the vibration of the water tank cover 21 accompanying the rotation of the drum 11 is synchronized with the drum 11, the period of the amplitude is substantially the same, and the relative position does not change.
The irradiation range X for irradiating the inside can be kept substantially the same range, and the visibility in the drum 11 is improved.

Furthermore, the position (shaded part S) which differs from the blowing direction of the air supply port 22 which blows off the illuminating device 24 with hot air.
Since the hot air blown from the air supply port 22 is difficult to directly hit the lamp 24, the deterioration of the lighting device 24 and the LED 24a due to heat can be prevented, and the lighting device 24 and the LED 24a are frequently replaced. It becomes possible to use for a long time without doing.

The entire surface of the base 24a1 on the side where the LED 24a is provided is silk-printed in white, so that when the illumination device 24 is viewed, the illumination device 24 becomes inconspicuous, and light emitted from the LED 24a is reflected. In addition, the inside of the drum 11 can be illuminated more brightly.

Furthermore, the inside of the drum 11 can be illuminated more brightly by applying a mirror finish to the surface of the storage portion 24d1.

Further, although the lighting device 24 uses the LED 24a, a light bulb or the like may be used. Moreover, the illuminating device 24 may be comprised by LED24a single-piece | unit. In this case, the lighting device 24 is attached in such a manner that the mounting opening is formed by, for example, a threaded hole, and a cylindrical LED 24a having a threaded portion on the outer periphery is coated with a heat-resistant sealing material between the screws. Screwed in the state. Also in this case, the light emitted from the LED 24a is attached so as to have a directivity direction obliquely downward in the drum 11.

The hot air generated at 3 passes through the air supply path 52a from the duct 41 as indicated by the arrow indicating the air flow in FIG. Hot air is blown out vigorously into the drum 11 (air flow in the direction of arrow T).

Accordingly, as shown in FIGS. 7 and 8, the direction in which hot air is blown from the air supply port 52 (drum 11).
It is difficult for hot air to directly hit the lighting device 24 provided at a position different from the inner direction), and a part of the air flow in the direction of arrow T is diffused in the middle of the drum 11 and brought into contact with the laundry being stirred. Dry the laundry.

The hot air that has come into contact with the laundry merges near the drain port 17 to form an air flow in the direction of arrow A, and the air in the drum 11 is circulated and dried as described in the first embodiment. .

According to the second embodiment of the present invention as described above, the air supply path 52a is protruded from the water tank cover 21 to the inside of the water tank cover 21, and the air supply opening 52 which is the outlet of the hot air supply path 52a is drummed. 11, the hot air is blown directly into the drum 11, so that the illuminating device 24 provided on the water tank cover 21 is not easily hit by the hot air, and the illuminating device 24 is heated.
In addition, the deterioration of the LED 24a can be prevented, and the lighting device 24 and the LED 24a can be used for a long time without frequent replacement.

In the present embodiment, the air supply passage 52a is formed so as to protrude into the water tank cover 21, but the hot air generated by the hot air generating device 43 may be blown directly toward the drum 11 instead of toward the water tank cover 21. The air supply path 52a guides the hot air, and the direction of the opening of the air supply port 52 may not be directed to the water tank cover 21 but may be directed to the inner side of the drum 11.

In the present embodiment, the air supply path 52a is formed so as to protrude as a part of the water tank cover 21, but the air supply path 52a does not need to be formed integrally with the water tank cover 21, and the air supply path 52a is a separate member. It is good also as a structure produced and attached to the water tank cover 21. FIG.

Next, a third embodiment of the drum type washer / dryer according to the present invention will be described with reference to FIGS.

FIG. 13 shows a perspective view of the drum type washing and drying machine. In the following description, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different points are described below.

That is, in the second embodiment, the air supply port 22 is formed on the right side of the upper portion 21 b of the water tank cover 21, and the lighting device 124 is provided in parallel at a position near the left side of the air supply port 22.

Further, a see-through window 132 which is a circular see-through portion is provided at the center of the door 28. The see-through window 132 has a front glass 133 provided on the front portion 1a side and a circular dish container shape from the door 28. And a rear glass 134 which is a bulging portion having a shape bulging rearward (drum 11 side). In the state where the door 28 is closed, the rear glass 134 is positioned in front of the laundry input port 26 of the drum cover 25 inside the bellows 35 (see FIGS. 11 and 12).

Further, as shown in FIGS. 11 and 12, an inclined surface 100 is formed on the outer periphery of the rear glass 134 at a position facing the illumination device 124 and the air supply port 22 (see FIGS. 10 and 13). The shape of the inclined surface 100 is the front on the outer periphery of the rear glass 134 with the door 28 closed (front glass 33 side), and faces the center point of the lighting device 124 and the air supply port 22 on the water tank cover 21. For example, the position V is formed in a manner inclined at an angle of 45 degrees toward the rear.

The inclined surface 100 is configured such that a light reflecting surface 101 is formed so that light emitted from the illumination device 124 can be reflected and guided into the drum 11.
